Connecting readers / serial devices

NOTICE
Correct usage
When connecting non-specified devices to the RF120C, it is possible that the connected
device may be destroyed.
A pre-assembled cable therefore permits the optimum and simple connection of the reader.
The standard version of the connecting cable is available in lengths 2 m, 5 m and 10 m.
Figure 3-2
To connect the cable, open the lower door in the housing as shown in the figure and connect
the reader or serial device using the D-sub cable and the 9-pin D-sub socket of the
communications module.
NOTICE
Attaching strain relief
When a SIMATIC MV320 optical reader is connected to a communications module, you need
to secure the MV320 connecting cable with strain relief. This strain relief can be provided by
means of a cable clamp, for example. Secure the MV320 connecting cable by fixing the
cable to the rack between the D-sub connector and the cable curve of the MV320
connecting cable using the strain relief.
